especially since PC gamers have been gaming at 1080p with decent frame-rates, for more than a decade now (now embracing 4k).
I'd love to see what 4K looks like in person. I imagine it're pretty spectacular when you consider 4K is to 1080p (the holy grail of console gaming) as 1080p is to 860x540 (would have been considered totally unacceptable even last generation).
